1) Homozygous at that locus.
2) The human tailbone. It is what remains of a tail that we no longer need.

Recessive allele: The term "recessive gene" refers to an allele that motives a phenotype (seen or detectable function) it extremely is barely considered in homozygous genotype (an organism that has 2 copies of an identical allele) and under no circumstances in a heterozygous genotype. every person has 2 copies of each gene on autosomal chromosomes, one from mom and one from father. If a genetic trait is recessive, someone desires to inherit 2 copies of the gene for the trait to be expressed. subsequently, the two mum and dad ought to be agencies of a recessive trait to be sure that a new child to particular that trait. If the two mum and dad are agencies, there's a 25% risk with each new child to coach the recessive trait. The term "recessive gene" is a factor of the regulations of Mendelian inheritance created via Gregor Mendel. Examples of recessive genes in Mendel's properly huge-unfold pea plant experiments comprise those that make certain the colour and shape of seed pods, and plant top.

Homozygous
Human tailbone (vestigial means lost its original function)

The first one is
homozygous
The sencond one is the human tailbone

1) homozygous (for example aa or AA)
2) human tailbone (our ancestors had tails, we don't but the tailbone is a vestigal structure)

Am I right or wrong? At this point I'm just taking a guess, cause I don't really like biology all that well.
But hey! That's awesome that you like it so well!
maybe you can give me tips or advise on it sometime, lol.
